Objective To test different expression protein markers of the serum from B-cell non-Hodgkin lymphoma(B-cell NHL) between diffuse large B-cell lymphoma(DLBCL) and follicular lymphoma(FL)patients using sudace enhanced laser desorption/ionization-time of flight-mass spectrometry(SELDI-TOF-MS)protein chip technology. Further, to test different expression of the protein markers of B-eell NHL patients after chemical therapy in order to discuss clinical significance. Methods Different expression of protein markers were analysed in serum between 54 B-cell NHL patients and 27 healthy volunteers by using SELDI-TOF-MS WCX-2 pertein chip. Meanwhile different expression of protein markers relative to pathology classification between 23 DLBCL patients and 12 FL patients were screened; and protein markers which affected prognosis of 23 DLBCL patients were screened. Results There were five specific marker proteins in 54 B-cell NHL patients and 27 healthy volunteers. Their relative molecular weights were 7974, 15 938, 3398,8564, and 8692. The protein markers of 7974 and 15 938 were at high level in patients and the protein markers of 3398, 8564 and 8692 were at low level in patients. There were two protein markers which affected the prognosis, with better outcome when the expression of 4795 and 4998 were increased. Conclusion SELDI-TOF-MS protein chip technology is a quick, easy and convenient method, with high-throughput analyzer which can screen several relatively specific protein markers from the serum of patients to diagnose B-cell NHL The relatively specific protein markers can be used to make pathology classification and to judge the prognosis of B-cell NHL, and have better clinical value.

Objective To research correlation of serum protein spectrometry and lymphoma markers for diffuse large B cell lymphoma (DLBCL) patients. Whether there is relative between the protein and prognosis will be further researched. Methods Serum protein spectrometry of 62 DLBCL patients was detected by the SELDI-TOF-MS technique and Weak cation exchange 2 (WCX2) chip. Lactate dehydrogenase (LDH) was detected by biochemistry method. Beta-2-microglobulin (β2-MG) and cancer antigen125(CA125)were detected by enzyme-linked immunosorbent assay (ELISA). The level of LDH, β2-MG and CA125 for DLBCL patients between 11×103～12×103 protein expressed positively and negatively was analyzed. Meanwhile,correlation analysis and survival analysis were done. Results LDH, β2-MG and CA125 in 11×103～12×103protein expressed positive group were (523.30±435.96)U/L, (3.23±1.24)mg/L, (81.07±61.39)U/L respectively,and they were higher than that in negative group (P＜0.05). 11×103～12×103 protein was positive correlated to LDH, β2-MG and CA125 (P＜0.01). The survival time in 11×103～12×103 protein expressed in positive group,in which median survival time was 11 months, was shorter than that in negative group(P ＜0.01). The survival time in LDH normal group was longer than that in increased group(P ＜0.01). The survival time of β2-MG and CA125 had no significant difference between increased group and normal group. Conclusion LDH and 11×103～12×103 protein are expected to be prognosis indicators for DLBCL patients.

Objective This study investigated the application value of waist-to-height ratio (WHtR), body mass index (BMI), and waist-to-hip ratio (WHR) in screening for type 2 diabetes mellitus (T2DM) and high risk of T2DM. Methods A total of 7 582 subjects aged 40-75 years were randomly selected and stratified based on the results of an oral glucose tolerance test (OGTT) administered during a standard screening for T2DM in the Shougang community.Three anthropometric indices(WHtR,BMI,and WHR) were compared, with the optimal cutoffs for WHtR, BMI, and WHR identified using receiver operating characteristic curve (ROC) analysis. Using multivariate logistic regression analysis and the area under the curve(AUC)of ROC,the associations between BMI,WHR,and WHtR and T2DM were analyzed by group: normal glucose tolerance group (n= 3 080), T2DM high-risk group (n= 2 992 cases), and T2DM group(n=1 510).Results Logistic regression analysis showed that BMI,WHR,WHtR,and family history of diabetes were positively correlated with T2DM and high risk of T2DM(P<0.05 and P<0.01,respectively);WHtR was most significant, with odds ratios of 90.409 and 69.285, respectively. WHtR had the greatest AUC under the ROC in men,whereas BMI had the greatest AUC in women.The optimal cutoffs values for the detection of T2DM were 0.51, 25.47 kg/m2, and 0.91 for WHtR, BMI, and WHR in men, respectively, and 0.52, 24.95 kg/m2, and 0.86 for WHtR, BMI, and WHR in women, respectively. WHtR was more efficient than WHR and BMI based on the AUC. The optimal cutoff values for detecting a high risk for T2DM were 0.51,25.30 kg/m2,and 0.91 for WHtR,BMI,and WHR in men and 0.51,24.81 kg/m2,and 0.86 for WHtR, BMI, and WHR in women, respectively. Conclusion Waist-to-height ratio may be a more effective index for diagnosing type 2 diabetes mellitus and identifying individuals at high risk for T2DM than BMI or WHR.

Objective:To compare the short-term clinical outcomes of robotic distal pancreatectomy(RDP) with laparoscopic distal pancreatectomy(LDP).Methods:PubMed, Embase, Cochrane library, Wanfang data, CNKI were searched systematically.Studies that compared short-term clinic outcomes between RDP and LDP groups were included. Observation indicators include: operation time, intraoperative blood transfusion rate, spleen preserving rate, spleen vessels preserving rate, conversion rate to open surgery, complication rate, severe complication rate, pancreatic fistula rate, severe pancreatic fistula rate, length of hospital stay, etc. The Meta-analysis was performed by using RevMan5.3.Results:Eleven non-randomized controlled trials with 791 patients meet the inclusion criteria.This Meta-analysis shows: compared with LDP group, RDP group was associated with higher spleen preserving rate ( OR=2.32, 95% CI: 1.07-5.04, P=0.03), higher splenic vessels preserving rate ( OR=3.07, 95% CI: 1.10-8.57, P=0.03), lower conversion rate to open surgery ( OR=0.58, 95% CI: 0.35-0.97, P=0.04), shorter hospital stay ( MD=-2.42, 95% CI: -4.30 --0.55, P=0.01), longer operative time ( MD=27.11, 95% CI: 9.06-45.16, P<0.01). There was no significant difference in overall complications, severe complications, pancreatic fistula, severe pancreatic fistula, and transfusion rate between the two groups. Conclusions:RDP showed a slight advantage in short-term outcomes, and it is worthy of applying in large medical center. Further studies on the long-term outcomes of these surgical techniques are required.

Objective To systematically evaluate the association between frailty and risk of postoperative delirium.Methods Systematic review of literature was conducted using eight electronic databases:PubMed,Embase,CENTRAL,Web of Science,CNKI,CBM,VIP and Wanfang Data,and prospective cohort studies about association between frailty and postoperative delirium published before March 2017 were included.Two authors independently screened the literature,extracted the data,and assessed the quality using NOS Scale,and meta-analysis was conducted by RevMan 5.3 software.Results A total of eight studies involving 846 patients were included in this review.Meta-analysis showed that:frailty was associated with higher risk of postoperative delirium [OR=3.63,95％CI (2.06,6.40),P＜0.001].Subgroup analysis showed that:①Frailty assessment tool:Fried frailty criteria and other frailty assessment were associated with increased risk of postoperative delirium[OR=5.81,95％CI(3.54,9.77),P＜0.001],[OR=1.76,95％CI(1.06,2.92),P=0.03].②Age:frailty patients aged 60～74 had increased risk of postoperative delirium [OR=5.05,95％CI (3.14,8.12),P＜0.001],but for patients aged ≥ 75,frailty wasn't associated with postoperative delirium [0R=1.73,95％CI (0.99,3.00),P=0.05].③Type of surgery:for cardiovascular and non-cardiovascular surgery patients,frailty was associated with increased risk of postoperative delirium [OR=3.40,95％CI (1.64,7.05),P＜0.001],[OR=4.95,95％CI (2.41,10.16),P＜0.001].Conclusion Frailty can increase the risk of postoperative delirium.In consideration of quantity and quality of included studies,the conclusion needs to be validated by multi-centered prospective cohort studies with large sample size.

Objective To explore the effect of nursing intervention based on the transtheoretical model and stages of change on breastfeeding knowledge, self-efficacy, and duration of breastfeeding in newly born pregnant women, aimed to provide reference for breastfeeding behavior health education model for pregnant women. Methods The 130 primiparas who came to the hospital graded a class- three of Shanxi Province for perinatal examination were selected as the research subjects from May to June in 2017 , they were divided into test group and control group by random digits table method. In the control group, the normal breastfeeding health guidance was carried out in the three stages of prenatal, hospitalized and after discharge. The test group divided the primipara from the beginning of pregnancy to 6th months postpartum period into 5 stages according to transtheoretical model and stages of change. The new strategy of breastfeeding should be formulated and implemented according to different stages and behavior changing processes. Results The total score of breastfeeding knowledge of primipara were (8.76±1.14), (8.92±1.21), (9.90±1.27), (9.94±1.29) points in control group before intervention, the 3rd day, the 42nd day and the 6th month after delivery, and they were (9.11 ± 1.42), (12.02 ± 1.64), (13.04 ± 1.67), (15.00±1.83) points respectively in test group, the differences were statistically significant(Ftime= 51.823, Fgroup=10.406, Finteractive=56.641, all P < 0.05). The total scores of breastfeeding self-efficacy of primipara were (84.62 ± 1.14), (88.96 ± 1.41), (86.65 ± 1.47), (84.31 ± 1.57) points respectively in control group before intervention, the 3rd day, the 42nd day and the 6th month after delivery, while in test group they were (84.98 ± 1.20), (104.02 ± 1.42), (111.00 ± 1.45), (120.04 ± 1.40) points, the differences were statistically significan (Ftime=12.592, Fgroup=229.674, Finteractive=79.955, all P<0.05). The pure breastfeeding rates of primipara were 60.0％(33/55) , 41.8％(23/55), 21.8％(12/55) in control group on the 3rd day, the 42nd day and the 6th month after delivery, they were 84.7％(50/59), 76.3％(45/59) , 49.2％(29/59) in the test group. The differences was statistically significant (χ2=8.804, 14.038, 9.235, all P <0.01). Conclusion Breastfeeding intervention based on the theory of behavioral staged transition can help primipara to improve breastfeeding knowledge and self-efficacy, and improve breastfeeding status.

Objective:To explore the association between levels of thyroid-stimulating hormone (TSH) on admission and prognosis of patients admitted to intensive care unit (ICU).Methods:The data were collected from patients who were admitted to the ICU of the Beth Israel Deaconess Medical Center in the United States from 2001 to 2012 with available TSH test records within 24 hours after the ICU admission via the Medical Information Mart for Intensive Care-Ⅲv1.4 (MIMIC-Ⅲv1.4). Information including gender, age, ethnicity, type of admission, mechanical ventilation (MV) or renal replacement therapy (RRT) received on admission, comorbidities, and TSH test records within 24 hours after the ICU admission were collected. The sequential organ failure assessment (SOFA) score, simplified acute physiology score Ⅱ (SAPS Ⅱ) and the comorbidities index Elixhauser (SID30) score were calculated according to the parameters. The primary outcome was hospital mortality. Differences in baseline characteristics and prognosis were examined between patients with normal TSH levels and abnormal TSH levels which was determined according to a dichotomous variable provided by the data. Multivariable Logistic regression was used to analyze the association between TSH levels and prognosis after adjusting for confounding factors. A sensitivity analysis was conducted which categorized the study population as three groups (i.e., decreased, normal, and elevated TSH levels) using the range of 0.30-3.00 mU/L as the normal range of TSH.Results:A total of 3 425 ICU patients were enrolled in the study, of which 2 692 (78.60%) were with normal TSH and 733 (21.40%) were with abnormal TSH. There was no statistically significant difference in gender, age, ethnicity, type of admission and the ratio of MV between the normal TSH and abnormal TSH groups. Compared with normal TSH group, the patients in abnormal TSH had a higher SOFA, SAPS Ⅱ and SID30 scores as well as the ratio of RRT [SOFA score: 4 (2, 7) vs. 4 (2, 6), SAPS Ⅱ score: 38.02±13.76 vs. 36.53±13.75, SID30 score: 11 (4, 22) vs. 11 (0, 20), RRT ratio: 5.32% (39/733) vs. 3.49% (94/2 692), all P < 0.05]. The hospital mortality of patients in normal TSH was significantly higher than that of those in abnormal TSH [9.82% (72/733) vs. 5.94% (160/2 692), P < 0.01]. After adjusting for confounding factors, abnormal TSH was significantly associated with hospital mortality [odds ratio ( OR) = 1.71, 95% confidence interval (95% CI) was 1.24-2.35, P = 0.001]. In the sensitivity analysis in which the range of 0.30-3.00 mU/L was used as the normal range of TSH, compared with normal TSH, decreased TSH ( OR = 2.36, 95% CI was 1.40-3.97, P = 0.001) and elevated TSH ( OR = 1.44, 95% CI was 1.05-1.98, P = 0.023) were both significantly associated with increased hospital mortality. Conclusion:An abnormal level of TSH within 24 hours after admitted to ICU is an independent risk factor for hospital mortality among ICU patients.

The orbitofrontal cortex (OFC) is involved in diverse brain functions via its extensive projections to multiple target regions. There is a growing understanding of the overall outputs of the OFC at the population level, but reports of the projection patterns of individual OFC neurons across different cortical layers remain rare. Here, by combining neuronal sparse and bright labeling with a whole-brain florescence imaging system (fMOST), we obtained an uninterrupted three-dimensional whole-brain dataset and achieved the full morphological reconstruction of 25 OFC pyramidal neurons. We compared the whole-brain projection targets of these individual OFC neurons in different cortical layers as well as in the same cortical layer. We found cortical layer-dependent projections characterized by divergent patterns for information delivery. Our study not only provides a structural basis for understanding the principles of laminar organizations in the OFC, but also provides clues for future functional and behavioral studies on OFC pyramidal neurons.
